Application filed January 12, 1914.

To all whom t may concern Be it known that l, ARTHUR 0. BUSCH, a citizen of the United States, and a resident of Flasher', in the county of Morton and State of NorthDalota, have invented certain new and useful Improvements in Spring-Motors, of which the following is a speciiication.

This invention relates to spring motors which are particularly adapted for fans which are actuated by springs and designed to move the air in inclosed spaces.

The principal object of the invention is to obtain a fan to move the air in a room, chamber, hall or other inclosed space, which is actuated by a spring and which will run for a considerable time after being wound up.

A further object is to obtain a device which will not require frequent oiling, and which will not produce a great amount of friction in the train of wheels actuated by the spring of the device.

A further object is to produce a device which will present a good appearance; which is easily wound; which is not liable to break or get out or order, and which is portable.

In the drawings, which illustrate a device embodying this invention Figure l is a vertical section of the shell and an elevation 0f the movable parts of said device. Fig. 2 is a side elevation of the cap of the shell and Fig. 3 is side elevation of the base of said cap. Fig. 4 is a horizontal section on line 4-4 of Fig. l, viewed in the direction indicated by the arrows. Fig. 5 is a top plan view of the gear train of the device and of the body of the box in which said train is inclosed. Fig. 6 is a section on line 6--6 of Fig. 5, viewed in the direction indicated by the arrows.

A reference letter applied to designate a given part indicates said part throughout the several figures of the drawing wherever the same appears.

X is the outer shell holding the movable parts of the device, X1 is a base and journal bearing attached to the upper shell X, and X2 is a cap which fits on the base X1.

Y is a fan shaft which is journaled in bearings Y1 and Y2, in base X2.

Z is a vertical shaft journaled at its upper end in the journal bearing Z1 in base X1.

W is a beveled gear wheel on the upper end of shaft Z and W1 is a beveled gear wheel Specification of Letters Patent.

on fan shaft Y. The teeth of wheels W and W1 intermesh so that the fan shaft is turned by the rotation of the vertical shaft.

U is a non-rotatable shell in which the spring Ul is contained; and V is a box or shell in which the gear train of the device is contained. BOX or shell V is provided with a cover V1, and said cover is provided with a journal bearing V2 in which the lower end of the vertical shaft Z is journaled.

V3 is a collar attached to the vertical shaft Z, and V* are balls on which collar V3 rests and rides as it is turned by the turning of shaft Z. Shaft Z thus rests on said balls and is supported thereby.

a is a gear wheel which is loosely mounted on the end of the hollow bearing c1 of drum a2. Drum a2 is provided with an additional hollow bearing (a3) and both of said hollow bearings, (al and a3) are journaled in the bottom and top plates of the shell U. The inner end of spring U1 is attached to hollow drum c2, and the outer end thereof is attached to the vertical wall of shell U.

Gear wheel a intermeshes with gear wheel A which is rigidly secured to shaft b. Shaft Zi is journaled at its upper end in step b1 and at its lower end in bearing b2 on the bottom of boX or shell V. Step b is attached to the upper face of the cover V1 by rivets or bolts 3. Shaft Z9 thus extends above the cover V1 and passes through an aperture provided therefor, fitting said aperture reasonably close so that half hard grease or oil in said shell Y will not flow through said aperture.

C is a pinion on shaft Z intermeshing with the teeth of gear wheel B. D is a gear wheel on said shaft d, intermeshing with pinion E on shaft e.

F is a gear wheel on shaft e, intermeshing with pinion G on shaft g.

H is a gear wheel on shaft g intermeshing with pinion l on shaft la; and J is a gear wheel on shaft 7L inter-meshing with pinion K on vertical shaft Z.

lt will be observed that the vertical shaft Z passes through the hollow bearings a1 and a3 of drum a2, and through the cover V1 of box or shell V. The aperture in said cover which is provided for the vertical shaft to pass through fits so closely to said shaft that no oil or grease will How from boX V around said vertical shaft. The several shafts d, e, g and L are journaled withink the boX V and do not extend through the bottom or cover thereof, (see bearings f, L is an aperture in the bottom of box through which oil or grease is introduced to nearly fill said shell. A plug, Z, is fitted on to aperture L after oil or grease of a suitable,

consistency is introduced into box or shell V to illvor nearly ill said boX.

y M is a ratchet wheel on sprocket wheel N. Backward rotation of the ratchet Wheel M without corresponding movement of the gear train is prevented by pawl m which is pivoted on the upper face of wheel a.

1 Hollow 'bearing a3 is rigidly secured to the hub n ot sprocket wheel N so that turning of said sprocket wheel turns hollow drum a2 and winds spring U1. The unwinding of said spring actuates the above described train of gear wheels, thus rapidly turning vertical shaft Z and fan shaft Y. Sprocket wheel N is turned by means of sprocket chain. O, wheel P on shaft p, ratchet wheel p1, and handle p2, (which is provided with a ratchet p3 engaging with ratchet 2.91).

Q are bosses on the under side of the bottom of shell V, adapted to receive bolts or screws @to secure said shell V to the bottom of shell X. The attachment of the base X1 to the shell X consists in placing the cir- Gopies of this patent may b obtained for cular part or portion X3 of said base X in the upper circular endof shell X, (see Fig.

l).l Said base X1 can then be turned in a K horizontal plane.

A casing, shells in said casing rigidly secured thereto, a hollow hub and a spring in one of said shells, journal bearings to said hollow hub in the hub containing shell,`

means adapted to turn said hub in one direction to wind said spring and to permit said hub to turn in the opposite direction as said spring unwinds, and a gear train in theother of said shells, in combination with a vertical shaft extending through said hollow hub and adapted to be driven by saidvgear train, bearings to said vertical shaft, one of said bearings positioned above and one below said hub containing shell, and a conve cents each, byinddressing the Commissioner of Patents- Washington, D. C."
